Belimo B340+AFRB24-SR Characterized Control Valve Cv Spring Return - 1.5 3-Way 37 24V

The Belimo B340+AFRB24-SR is a 1.5-inch three-way characterized control valve (CCV) paired with an AFRB24-SR proportional actuator, designed for precise flow control in commercial HVAC applications. This valve assembly features a 37 Cv rating, providing excellent flow capacity for medium-sized heating and cooling systems.

Key Features:

• 1.5-inch NPT threaded connection for standard piping integration
• Three-way mixing or diverting valve configuration for versatile system design
• 37 Cv flow coefficient for robust flow capacity
• 24V proportional actuator with 2-10 VDC modulating control signal
• Spring return functionality for fail-safe positioning during power loss
• Characterized control for linear flow control and precise temperature regulation
• Bronze or brass valve body construction for durability and corrosion resistance

This valve assembly is ideal for chilled water, hot water, and glycol solution applications in commercial buildings. The proportional control allows for precise modulation based on control signals from building automation systems or zone controllers. The spring return feature ensures the valve returns to a predetermined safe position in the event of power failure, protecting system equipment and maintaining building comfort.
